Listener Ndanusa in Ghana, is gazing up at the stars, and wondering what keeps our universe in balance? Ndanusa knows a thing or two about the stars, and he knows that they use up hydrogen as they burn, and release helium. And he’s wondering, is there something out there which does the opposite? Something that uses up helium, and produces hydrogen, to keep the universe in perfect, chemical equilibrium? Presenter Alex Lathbridge goes on a journey to answer his questions and delves into the blackness of deep space, the ancient origins of our universe, and the complex physics of the stars. He pops into the Ghana Radio Astronomy Observatory, just outside Accra, where astrophysicist Dr Proven Adzri helps him peer into the earliest few seconds of our universe, and find out what set the stars burning. And at Kwame Nkrumah University of Science and Technology, Dr Linus Labik talks him through what’s going on at the atomic level. And in the deep blackness of the night, up above the tree canopy of Kakum National Park, he takes a peek at the stars for himself. Local guides Chris and Kwabena explain how much meaning there is behind the stars in the night sky.
